I'd like to see access to the inbox, too. It would be great to be able to clients that backup and manage the inbox.

Also, I'm concerned that if the API manages to cause clients to happen, and people start DWing from the phones or desktop apps or whatever, and those don't support the inbox, it will become even more impossible to direct-message people, because those users will never see anything about it, unless they have turned on email notification (which apparently is not on by default?)

I don't just want the API to support the inbox, I kinda want inbox support to be mandatory for DW posting/reading clients. Because I'm afraid that otherwise clients will turn the inbox into dead.letter.
